趣味性听觉材料对驾驶疲劳的作用：来自EEG的证据

疲劳驾驶是诱发交通事故的重要因素,研究驾驶疲劳的有效干预方法具有重要意义。本研究通过让驾驶员在驾驶模拟器中完成1小时的单调驾驶任务来诱发驾驶疲劳,同时记录驾驶员主观疲劳、驾驶绩效和脑电θ波功率,来探究趣味听觉材料是否可以缓解驾驶疲劳。结果发现,在单调驾驶条件下收听趣味听觉材料的驾驶员脑电θ波功率高于控制组,表明收听趣味听觉材料不利于缓解驾驶疲劳。     

Cognitive competencies and aggressive behavior: A developmental study

A number of studies have demonstrated that increased socially related cognitive skills are associated with decreases in aggressive behavior. However, the link between aggression and intelligence or academic skills is less evident. While some research indicates that poor academic performance is related to aggression, it is unclear which components of intellectual ability and performance are critical to the management of aggressive behaviors. In two independent longitudinal studies of elementary school-age children, the relationship among several aspects of cognitive competence and several aspects of aggressive behavior were examined. The results of the first study showed that aggressive behavior observed in kindergarten children was more closely related to academic performance in the first and second grades than to general cognitive ability (IQ). The results of the second study, a comprehensive three-year investigation of upper elementary school-age children, indicated that teachers' assessments of aggression and parents' ratings of cruelty were consistent over time for boys, but not for girls. The intercorrelations among aggression measures within each of the three years also revealed stable sex differences. Boys identified as aggressive in the classroom were more likely to be perceived as aggressive, cruel, and/or delinquent at home, but for girls, there was little correlation between aggression at school and in the home. The analyses relating measures of cognitive functioning to indices of aggressive behavior made clear the importance of discriminating among various facets of these psychological constructs. IQ had a negligible relationship with aggression and a weak inverse relationship to delinquency. An overall index of cognitive functioning was a somewhat more consistent negative correlate of aggression, cruelty, and delinquency, especially for boys. A similar pattern was found for the correlates of academic performance. Academic disability was strongly related to delinquency in boys, and to a lesser degree to aggression in boys. Of the several cognitively related factors that were explored, Low Need Achievement manifested the strongest and most consistent relationships with the different facets of aggression and antisocial behavior, especially in boys. The implications of these results for psychological interventions in the school are discussed.     

Sleep, watchkeeping and accidents: a content analysis of incident at sea reports

The unique profession of seafaring involves rest and sleep in a 24-h-a-day work environment that usually involves time-zone crossings, noise, heat, cold and motion. Sleep under such conditions is often difficult to obtain, and sleeping and sleep loss are often related to fatigue and contributory to accidents. This study aims to determine how accident investigators report sleep in Incident at Sea Reports and subsequently analyse the relationships between sleep, fatigue and accidents in these reports.The full text of 44 Incident at Sea Reports was coded and analysed using NUDIST software. This sample included collisions and groundings reported since 1991, where significant human factors contributed to the incident. The Incident at Sea Reports were electronically searched for reference to sleep and content was indexed against parameters such as fatigue behaviours, time of day and contributing personnel. Incident at Sea Reports incorporate three levels of reference to sleep, analysis of which may associate sleeping and sleepiness with accident causation. The highest level of reference unequivocally associates either being asleep, or being sleep deprived with accidents, but not always with fatigue. At an intermediate level, reference to the conflicting pressures of work and sleep on board fishing boats and ships suggests a work environment that is not conducive to obtaining sufficient sleep, and accident investigators are usually unable to link the watchkeeping environment with fatigue as a contributing factor. At the lowest level of association, reference is made to the integrated nature of sleeping and work on board.     

爆发怒与潜在怒及其在认知操作中的功能

研究旨在证明;实验1.实验室人工诱发婴儿被试愤怒情绪被划分为爆发怒与潜在怒两种愤怒表现形式,它们在婴儿进行的“迂回”作业操作中显示了不同的功能作用：爆发怒被试的操作效果显著优于潜在怒被试。实验２．以实验１同样的方法诱发婴儿被试愤怒情况下,在另一项“寻找”作业中验证了爆发怒与潜在怒两种愤怒形式确实具有不同的功能作用,实验２以心率水平测量作为验证指标。     

领悟社会支持与中小学教师工作绩效：有调节的中介模型

基于社会支持的缓冲器模型和自我调节理论,本研究探讨了领悟社会支持对中小学教师工作绩效的作用机理。通过对510名中小学教师的调查与分析,结果表明：领悟社会支持与中小学教师工作绩效呈显著正相关;心理授权在领悟社会支持与工作绩效间起中介作用;未来工作自我清晰度调节了心理授权在领悟社会支持与工作绩效之间的中介作用。较之低未来工作自我清晰度的教师,中介效应在高未来工作自我清晰度教师中更显著。     

用中国人个性量表(CPAI)预测国有企业中高层管理者的绩效

本研究用中国人个性量表 (CPAI)测量了某国有企业的 3 8名中高级管理人员 ,并获得了他们最近的上司评定绩效资料。相关分析表明 ,CPAI的和谐维度与工作能力和工作态度的多个指标有正相关 ,CPAI的领导维度与沟通能力有正相关。与假设相反 ,老实 -圆滑和务实与沟通能力有负相关 ;越外控的员工 ,其合作态度的评价越高。这可能表明了国企管理的某些特点对人格—绩效关系的影响。本研究揭示了一些被西方心理学家忽视的人格维度对于中国企业人力资源管理的重要意义。     

组织中绩效压力的双刃剑效应

市场经济的复杂多变给组织生存与发展带来诸多挑战,组织往往对员工提出高的绩效要求,绩效压力已成为普遍现象。现有研究大多关注绩效压力的消极效应,存在忽视其积极结果及理论视角较窄等不足。因此,系统、全面地认识绩效压力的双刃剑效应,有助于组织充分发挥绩效压力的积极效应及阻遏其消极效应。通过系统地回顾和梳理相关研究,在将绩效压力影响效果的研究分为积极、消极和二者并存的曲线效应三个类别后,引入压力认知评价理论、资源保存理论等理论厘清研究背后的解释机制。最后,基于以上梳理分析,未来研究应进一步拓展组织中绩效压力的双刃剑效应及其边界条件,从而更全面地认识组织中绩效压力所产生的影响。     

领导风格与员工创新绩效关系的元分析：基于自我决定视角

领导对员工创新起到重要作用。什么样的领导风格与员工创新相关更高?实际研究中存在一定争议。为了回答这个问题,基于自我决定理论,我们提出一个理论框架,来解释不同领导风格与员工创新相关系数的差异。我们使用元分析汇集432篇独立的实证研究的证据(中文研究229篇,英文研究203篇,样本总量达161599),来检验我们的假设。研究发现：(1)交易型领导、伦理型领导、变革型领导、服务型领导、领导-成员交换、授权型领导、包容型领导及真实型领导与员工创新绩效之间均存在显著的正相关,且相关递增;(2)个人主义、绩效评价方式、数据收集时间点、领导风格测量方式、创新测量方式以及发表语言部分调节领导风格和员工创新绩效的关系。研究结果符合理论预测,研究促进自我决定理论的发展。更为重要的是,研究结论为管理者提供重要的实践意义,即使用合适的领导风格进而促进员工创新。
